| 1. A polymeric conductive composition comprising the structure [Hx-By-Tz]n,
wherein H comprises at least one functionalized head group capable of binding to a nanostructure surface or at least one head
group bound to a nanostructure surface;
wherein B comprises a first body structure B1 comprising a first conjugated organic moiety, and a second body structure B2
comprising a second conjugated organic moiety, wherein the first conjugated organic moiety is coupled at a first position
to a proximal functionalized head group or bound head group;
wherein T comprises at least one tail group between the first and second body structures and coupled to the first body structure
at a second position and wherein T comprises an alkyne moiety comprising between 2 and 22 carbons; and
